If you want your front end application to display certain properties of records in results lists, you must specify these properties in the fieldnames property of the resultslistdefaultconfig bean in assembler-context.xml.

For example, the following fieldnames definition specifies eleven properties that can be displayed with the records to which they belong:

<property name="fieldNames"> 
  <list>
   <value>product.id</value> <value>product.code</value>
   <value>product.name</value>
   <value>product.brand.name</value>
   <value>product.short_desc</value>
   <value>product.short_desc.Snippet</value>
   <value>product.price</value>
   <value>product.min_price</value>
   <value>product.max_price</value>
   <value>product.img_url_thumbnail</value>
   <value>product.review.avg_rating</value>
   <value>product.review.count</value> 
 </list> 
</property>
